SPECIFICATION forming part (if Letters Patent No. 691,328, dated January 14, 1902.

' Application filed February 21,1901. Serial No. 48,284. (No model.) i

To all whom it may concern:

Be it known that I, ISAAC D. SMEAD,-a citizen of the'United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in a Combined Crematory and Heating System, of which theifollowing is a specification.

. My present invention pertains to a central plant for heating water and consuming garbage, refuse material, and the like.

In the annexed drawings, forming part of this application, Figure 1 is a vertical sectional view of a portion of the apparatus on the line 3 3 of Fig. 3; Fig. 2, a similar view taken at right angles to Fig. 1 on the line 44 of Fig. 3; Fig. 3, a transverse horizontal section taken on the line 1 1 of Fig. 1; Fig. 4., an enlarged vertical sectional view of a portion of the apparatus; Figs. 5, 6, and 7, simi lar views showing the same parts in different relations, and Fig. 8 a transverse sectional View. takenon the line 2 2 of Fig. 1.

The object of my invention is, primarily, to provide a furnace wherein refuse and like material may be burned to advantage, and, secondly, to construct a plant in connection with such furnace wherein the water heated in the boiler above the furnace is caused to traverse a system of pipes and be returned to the boiler to be again heated.

Referring to the drawings, A indicates a foundation upon which is supported a well or chamber B, in the upper portion of which is formed a combustion-chamber 0, having a central discharge-opening D and a series of smaller openings E to one side thereof, all of which communicate with the base of a stack or chimney F, in which is mounted the boiler or water-heater G. The fuel or combustion chamber 0 is divided ofi from the main or lower portion of the well or chamber B by a revoluble grate H, and, as will be seen upon reference to Fig. 2, suitable gearing is provided for imparting rotary motion to the grate- Said grate is formed with a central opening, beneath whichis mounted a hopper I, having a lateral opening communicating with a chute or channel J, which in turn is connected with an upwardly-extending chute or channel K. The channel J extends out me diately below thehopper I.

through the wall of the Well, and in said extension is mounted a sliding head or ram L, the forward end of which is stepped, as shown. inFig. 1. To the rear end of said ram there is connected a rack M, and a pinion connected through suitable gearing meshes with said rack and operates to move the ram up or down in said chute or channel J. When said ram is in its elevated or .uppermost position, the lower'or delivery end of the chute or channel K is of course closed. This part of the apparatus is designed to feed coal or other fuel to the grate.

Beneaththe hopperl and forming a downward continuation thereof is a trunk or cylindrical chamber N, the lower portion of which is somewhat larger than the portion lyingim- Laterally-ex tending trunks 0 open into the upper enlarged portion of the chamber N, as will be seen upon reference more particularly to Figs. 2 and 4. These trunks are designed more especially for the reception of garbage, refuse, and like material to be used asfuel and burned.

Mounted within chamber N and making a close fit with the walls thereof is a collar or sleeve P, the upper end of which is sharpened or beveled, forming a cutting edge. A head or ram Q is in turn mounted within the collar, and extending downwardly therefrom is abar R, having racks formed upon two opposite faces thereof, as best illustrated in Fig. 1. Said head or ram forms a close fit with the interior face of the sleeve or collar P and is designed after the collar has been elevated to the position indicated in Fig. 5 to be moved up in said collar and to discharge therefrom the material which has entered into the collar above the head through the trunk 0. Suitable gearing (best shown in Figs. 1 and 8) is employed for raising and lowering the rack. Upon reference more particularly to Fig. 8 it will be noted that the bar R is acted upon on opposite sides, so as to relieve it of all lateral strains and permit its free upward movement.

Mechanism must be provided to have the sleeve or collar P move up with the head or ram until said sleeve or collar'has reached its highest position and closedthe mouths of the trunks O,'and to this end are pivoted at or near the upper end of the bar R levers S, while at the lower end are two similar levers T, the upper and lower levers on each side being connected bya bar orlink U. Normally the levers S bear upon the inwardly-projecting shoulder V, formed on the lower end of the sleeve or collar, and as the rod R, with its head, is mdved upwardly the collar is carried with it. When the parts reach the position indicated in Fig. 5, the lower levers T come in contact with projections W, extending outwardly from the wall of the well or chamber in which the rod R works, and tend to trip said levers, forcing the upper pair of levers S out from beneath the inwardly-projecting member V, thereby permitting the head or ram to move up independently of the sleeve or collar to the position indicated in Fig. 7, wherein it will be seen that the head or ram is in such position that any material which was in the trunk N will be discharged there from up through the hopper I. The friction between the parts and the pressure of the material in the trunks 0 bearing against the side of the sleeve or collar will tend to hold it against retrograde movement until the head or ram Q descends and comes in contact with in the wall of the chamber for-access to'the ash-receiving plates. A somewhat smaller opening 0 is formed in the wall of the chamber beneath the grate for the purpose of admitting air to aid in the combustion of the material and is in direct communication with a fan or blower c.

The fire-chamber O is formed as illustrated in Figs. 1, 2, and 3. It will be seen that it is provided with a lining in which is a series of openings (1, which communicate with a space or chamber 6, said space or chamber extending from a point near the grate upwardly to and in line with the openings 01. A partition or partitions f are formed in said chamber e and extend around spirally therein, so that the air which enters at the lowermost part thereof from a fan or blower g must traverse through the various flights formed in the chamber and in so doing absorb some of the heat from the surrounding walls,so that when it passes out of the openings or exits d it is heated to a sufficiently high degree as not to chill the fire, but, on the contrary, will aid proper combustion. reference to Fig. 3, the openings d, which extend out from the chamber e, are tangential As will be noted upon j .to the fire-chamber, so that'the hot air forced out from said openings has what may be termed a vertical or whirling movement, which in practice is found to be highly advantageous in burning garbage and like material. It is found that the material will burn to better advantage and more rapidly when this construction is employed than is the case wherethe air is not fed in this manner. An opening it is provided in the wall of the fire-chamber to afford entrance to the interior of the furnace.

The various sets of gearing are driven from a common shaft t, Fig. 1, so that all the parts may be timed in their movements, said shaft deriving its motion from anengine j, Fig. 8.-

The boiler G has outlet-pipes k, Figs. 1 and 3, extending from the uppermost section of the boiler, as is well understood, and a return pipe Z, connected with the lowermost section. The outlet-pipes are connected by a cross-pipe m, and said pipe m is in turn connected through a branch n with a coupling o, with which the pipes themselves are connected. Suitable valves are placed in the mains for controlling the flow of the water therethrough, and the pipe at is connected to a rotary pump 19 for the purpose of forcing water through the mains should occasion so require. The boiler is preferably made up of a series of sections or drums connected by pipes, as set forth in my application, Serial No. 727,560, filed on the 17th'day of August, 1899.

In feeding the fuel to the combustion-chamber above the grate it will be found preferable to force a charge of coalin above the garbage charge which is resting in the chamber when the plunger is in its lower-most position. If this is done when the plunger is elevated, the coal will be thrown toward the sides of the combustion-chamber, leaving the charge of garbage in the center surrounded by a. mass of coal, which of course soon becomes incandescent.

Havin g thus described my invention, what I claim is- 1. The combination of-a combustion-chamber, a grate mounted therein; a chamber lo cated beneath said grate; a trunk leading into said chamber; means for forcing out acharge of material from said chamber; and independent means for closing the opening of the trunk leading thereto.
